MARTIN BARRI, OF CAMBRIDGE, MASSACHUSETTS.

PNEUMATIC CASH-CARRIER.

SPECIFICATION forming part of Letters Patent No. 367,741, dated August 2, 1887.

Application filed November 29, 1886. Serial No. 220,170. (No model.)

To aZZ whom it may concern.-

Be it known that I, MARTIN BARRI, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Pneumatic Cash- Carriers, of which the followingis a full, clear,

and exact description.

This invention relates to improvements in pneumatic cash carriers such, for instance, as described and shown in Letters Patent of the United States, dated December 20, 1885, No. 333,397; and the invention consists in the combination, with a series of pneumatic tubes for the transmission of carriers, &c., therethrough, of a reservoir or chamber with which each tube has separate and independent communication, which is arranged and adapted to be opened and closed as desired, and said reservoir or chamber having communication with the bellows or other air-m0tor, all substantially as hereinafter fully described.

In the accompanying sheet of drawings is illustrated the present invention, Figure 1 being a front view representing in detail a cashiers desk or table or central station, showing a series of pneumatic tubes terminating thereat, arranged to be in communication with a common reservoir or chamber, which is in communication with a bellows for suitable operation thereof. Fig. 2 is a horizontal section on line 2 2, Fig. 1, with the top of the reservoir or chamber removed; Fig. 3, a vertical cross-section on line 3 3, Fig. 1. Fig. 4. is a vertical cross-section on line 4 4, Fig. 1, similar to Fig. 3, but showing some of the parts in different positions; Fig. 5, a detail elevation. Figs. 3, 4,- and 5 are enlarged.

In the drawings, A represents a bellows, circular in crosssection, having flexible sides B, and secured at its top to the board 0 of the frame I), and adapted to be operated by a treadlefE, connected to the bottom board, F, by cords a, each side running over pulleys G H, the treadle being pivoted to the side uprights, J, of the frame at b, and operated at d, at the front of the frame. This frame and bellows is placed under the table or board K, which represents the eashiers desk or table or central station, having aserics of pneumatic tubes, L, for the transmission of carriers or parcels therethrough, leading therefrom to their respective sale counters or single stations.

M is a box secured to the upper side of the table and making a chamber or reservoir, N, which has communication by a pipe or tube, P, with the bellows A, the pipe P extending through the central portion of the bottom board, F, of the box, through the table K and top board, 0, of the bellows, as shown in Fig. 1 more particularly. Secured to the front board, of this box M by screws 9 is a series of heads or receivers. R, in the same horizon tal line, each of which has a chamber, S, into which enters the end h of a tube or pipe, Q, forming a continuation of a pneumatic tube, L, which is secured in the upper end of said head.

Each of the heads are secured to the board over an opening, T, in the same, making communication between its chamber S and the reservoir-chamber N, as shown in section in Fig. 4.

Over each of these openings T within the chamber N is a flat valve, U, hinged at m, above the opening T, and arranged to swing down over it and close the same. On the back of each valve U is pivoted by one end a link, a, which at its other end is pivoted to a lever, V, fulcrumed at g to an arm, 1*, of the front board. Connected to the lower end of the lever V by the elongated slot S is a rod or bar, V, which extends through. an opening, it, in the front board,f, to the outside, having a handle, Y, for operation thereof. Pushing in the rod \V by the lever-connection closes and pulling it out opens the valve U, as shown in Figs. 3 and 4, respectively.

Hinged to each head It at a is a valve, Z, arranged to close the opening a in the bottom part of the head. This valve in its normal position is open, as shown in Figs. 1 and 3, and the head and its pipe connection and this valve are substantially the same in construction and operation as described in said patent.

A carrier, &c., to be transmitted through a pneumatic tube to a sales-counter or single station is first placed within the pipe in the head, as shown in dotted lines in Fig. 4, and the valve Z closed. The bellows are then operated by the treadle, which forces air up through the ICO pipe P, into and through the chamber N, into the head to the tubevl its valve U being first opened, and forcing the carrier along and through the tube until it is deposited at its respective sales counter or station, when the valve U is closed and the valve Z opened. Thus the air from the bellows or air-motor can freely pass to whichever tube P is placed in communication therewith by the opening of its valve U.

Having a common reservoir or air-chamber for the several pneumatic tubes to communicate therewith requires only one pipe or tube for communication with the bellows or air-motor, which obviously is a great improvement over a separate and independent pipe or tube and a valve to each pipe between each pneumatic tube and the bellows, as described and shown in said patent.

The several parts are made of any suitable material and secured together in any suitable manner, although it is preferable to make the box M ofwood and the heads to the tubes of metal; also, the several openings T can be arranged to be opened and closed in any suitable manner and otherwise than as herein particu larly described and shown.

The reservoir preferably has its top board, w, and back board, 11, secured in such manner that they can be easily removed when desir ous of getting at the valves and their operating parts, the several joints being made airtight.

Having thus described my invention, what I claim is- 1. In a pneumatic cash-carrier apparatus, the combination, with a series of pneumatic tubes for the transmission of carriers, &c., therethrough, of a chamber or reservoir having communication-with a bellows or other airlnotor, each tube havingcommunication with said chamber, and provided with means for opening and closing such communication.

2. In a pneumatic cash-carrier apparatus, the combination, with a series of pneumatic tubes for the transmission of carriers, 820., therethrough, of a chamber or reservoir having communication with a bellows or other airmotor, each tube having communication with said chamber, and provided with a valve foropening and closing such communication, ar-

ranged to be operated by a rod or bar from the MARTIN BARRT.
